Hi Guys,
I am troubleshooting a friends 2011 GSX 600 that can be started if the starter solenoid coil is given 12V with jumpers from the battery. I realize that this thread has to do with an 800 but the information here seems applicable. I also was pulling my hair out trying to locate the voltage regulator/ rectifier until I found this thread explaining that it is built into the ECM.
Once started it does not run very well and will die if the throttle is not partially open. This sled ran perfectly prior to the start (& reverse) button not working. In fact it ran great for quite a while after being started every time by jumping the starter solenoid.
The battery is new and it reads 12.8Vdc with the sled both off and when running. The battery receives no charging because the charging system relay is not being energized. I can jump 12vdc onto the charging system relay coil and then the normally open contacts of the relay will close connecting the battery to the sled's charging circuit.
The 5A & 30A fuses at the battery are good as is the splice in the harness for both fuses (30A fuse feeds the 5A fuse). If the power distribution circuit diagram posted by Daag44 is applicable to this sled then I believe that I have a bad ECM.
I also want to check the magneto stator as it provides the 60Vdc for the fuel injectors, fuel pump, ignition coils, oil pump, & capacitor which may be causing the poor running condition once started. I am confused however as to the purpose of the capacitor in an electric start machine. Is it in the 60V circuit to momentarily help the fuel pump, injectors & coils during cranking until the magnito stator is spun fast enough to take over?
How do I test the ECM, magneto stator & capacitor? Any other ideas as to what else might be the cause of this problem?
Thanks in advance for your help!
